Detailed Description

a CoordinateSystem is what the user sees: it is kept by KigPart to show the user a grid, and to show the coordinates of points...

it allows for weird CoordinateSystem's like homogeneous or projective... internally, it does nothing, it could almost have been an ordinary Object..., mapping coordinates from and to the screen to and from the internal coordinates is done elsewhere ( KigPainter and KigWidget... )

Member Function Documentation

virtual QString CoordinateSystem::coordinateFormatNotice ( ) const

pure virtual

This returns a notice to say in which format coordinates should be entered.

This should be something like: i18n( "Enter coordinates in the following form: \"(x,y)", where x is the x coordinate, and y is the y coordinate." );

Implemented in PolarCoords, and EuclideanCoords.

virtual QString CoordinateSystem::coordinateFormatNoticeMarkup ( ) const

pure virtual

Like coordinateFormatNotice(), but with HTML tags useful to have a rich text...

Implemented in PolarCoords, and EuclideanCoords.

virtual QValidator* CoordinateSystem::coordinateValidator ( ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual void CoordinateSystem::drawGrid ( KigPainter &  p, bool  showgrid = true, bool  showaxes = true  ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual QString CoordinateSystem::fromScreen ( const Coordinate &  pt, const KigDocument &  w  ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual int CoordinateSystem::id ( ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual Coordinate CoordinateSystem::snapToGrid ( const Coordinate &  c, const KigWidget &  w  ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual Coordinate CoordinateSystem::toScreen ( const QString &  pt, bool &  ok  ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.

virtual const char* CoordinateSystem::type ( ) const

pure virtual

Implemented in PolarCoords, and EuclideanCoords.
